Increased pressure in the ventricles means the heart has increased stress pumping blood to the respiratory system/ body.

What difference atria and ventricles fetal pig?

the difference between the ventricles and the atria is that the ventricles are thicker


What part of the blood is atria and ventricles?

The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.


Describe how heart contraction and relaxation influence coronary blood flow?

When relaxation or diastole is occurring in the atria blood flows through the atria and the AV valves into the ventricles. When contraction or systole is occurring in the atria the remaining blood that doesn't flow through during relaxation is pushed into the ventricles. As the atria relax, the ventricles begin contracting; ventricular pressure rises, closing the AV valves. Ventricular pressure continues rising until it exceeds the pressure in the large arteries stemming from the ventricles. The SL valves are forced open and blood is expelled from the ventricles into the aorta and pulmonary trunk. During this phase the ventricles relax because the blood is no longer compressed in their chambers. Blood expelled into the aorta and pulmonary trunk backflows toward the heart, which then closes the SL valves. During the ventricle contraction the atria stays in relaxation, filling with blood and when blood pressure on the atrial side of the AV valves exceeds that in the ventricles, the AV valves are forced open and ventricular filling begin all over again.


What are the four ventricles of the ventricular system?

the different types of ventricles are the left ventricle and the right ventricle.


What two components of the conduction system constitute the only electrical link between the atria and the ventricles?

The atrioventricular node and the bundle of HIS are the electrical conduction link between the atria and the ventricles.

Are the atria high pressure and ventricles low pressure?

no its the other way round


When atria relax ventricles do what?

When relaxed, the atria expand, and then the ventricles contract.


Do atria contract before the ventricles?

Yes, atria contracts before the ventricles.

Does high preesure or low pressure open atrioventricular valves?

High pressure within the ventricles (during ventricular contraction) closes the atrioventricular valves and prevents the backflow of blood into the atria. Low pressure within the ventricles (during ventricular relaxation) allows the atrioventricular valves to open, allowing blood to flow from the atria into the ventricles.


Function of atria?

Which phase in cardiac cycle is systolic pressure?

Blood flows into the relaxed atria while the ventricles contract. <rephrased> The ventricles contract, carrying blood into the aorta, and blood flows into the relaxed atria.

Why have the ventricles got thicker walls then the atria?

atria are just the receiving chambers, it is the ventricles that actually pump the blood into the pulmonary and systemic circuits


What makes the valves between atriums open and close?

There are no valves between the atria. The valves between the atria and ventricles close when the ventricles contract.


What part of your body has two atria and two ventricles?

I believe this would be your heart because that is the only time ventricles and atria are brought up.
